Well its been a long winter but the shop called Friday and was ready to to dyno my motor. I had this thing completely gone over cleaned and magna. The motor is a 500 hp carbed

I ended up going with 741 cam and Brodix BB2+ heads with a blower shop 250 blower. when i went down to the shop my camera battery was dead so i will put some pictures of the motor this week. I did take a picture of my dyno sheet so i will post that.

Let me know what you guys think and i could use some advice on a prop size.

The boat is 25 outlaw 1998. Thanks to everyone that helped out with advice.

Great power. You will need a stout lower unit to handle that. I am no expert, but the air fuel ratio looks a little lean, especially at the top. May want to inquire further on that.

You should be spinning that combo to at least 5500rpms. Did you go any higher on the rpms????

Do you have the printout that shows the atmospheric data and the correction factor used to correct the uncorrected torque and hp to the corrected values? That info would be helpful.

No we didnt go any higher griff i was planning on 5200.

I will see if i can get that data thundersuck.

Way lean.

Ditto.

Although Al Gore and his friends might not think so

So what should it be. The guy at the shop is saying its fine.

12.0 to 12.5 a/f

I just found out that the shop did not use my index regulator when they had it on the dyno would this have caused the problem.

I have no clue and this is why i paid these guys to set it up. So please i am open to any and all advice. Thanks
